Two antigens, probably polysaccharide in nature, were extracted from smoothgonococci.
One of these could be adsorbed on to red cells and sensitized these cells to the action of a …

The purpose of this work was: first, to devise improved methods of diagnosis of gonorrhea,
and, second, to determine whether typing of strains of gonococci could be made. The need …

Abstract 6 isolates of gonococci, adapted to growth in subcutaneous plastic chambers in
guineapigs, showed that one strain was more resistant to killing by human phagocytes and …

The ability of human monocytes to phagocytize and kill nonpiliated opaque (T3) and
transparent (T4) gonococci was investigated in a tumbling tube suspension assay. A serum …

Encapsulated forms of gonococci were obtained from seven of eight strains that were
studied. Except for the presence of a capsule, these strains were identical morphologically …

Many laboratory and clinical investigators have had difficulty in recognizing the different
colony types of Neisseria gonorrhoeae as displayed in black and white photographs …

Phagocytosis of Neisseria gonorrhoeae in tissue cell-cultures may protect it from the lethal
action of bactericidal agents. Type reversal from avirulent to virulent gonococci was not …

Cultivation of Neisseria gonorrhoeae in the allantoic cavity of 10-day chick embryos ensured
the following necessary properties for subsequent quantitive in vitro phagocytosis studies of …

Recent studies have demonstrated that virulent (Types 1 and 2) colonial variants of
Neisseria gonorrhoeae are highly resistant to phagocytosis by normal human …

Gonococci (strain bs3) passaged three times and harvested directly from plastic chambers
implanted subcutaneously in guinea pigs were compared with the parent strain (bs) grown …
